OPERATING BRAKES BY SIGNAL-CORD.

Specification of Letters Patent No. 10,321, dated December 20, 1853,

To all whom it may concern:

Be it known that 1, WM. G. CREAMER, of New Haven, in the county of New Haven, State of Connecticut, have invented a new and improved method of closing the brakes of a train of railroad-cars, whereby the engineer of the train can close all the brakes by pulling the bell or signal cord, which method does not in any way interfere with the use of the brakes in the usual way by the brakeman, nor does it interfere with the use of the cord for transmitting signals by the conductor to the engineer; and I do hereby declare that the following is a full and exact description.

To enable others skilled in the art to make and use my invention I herein describe its construction'and operation.

To any of the cars now in general use 1 afiix a weight or spring in connection with the brake which is kept in check by a small trigger shown at D D, plate 3. To this is attached a ring and cord at F. Underneath this trigger is a spring G, fitting .up to the underside and end of the trigger not so tight but that when it is pulled upward the ring will slip out when it (the trigger) is pulled in a vertical position. This rlng 1s connected with a small branch cord H reaching upward to the top of the car and thence forward about six feet and attached to the main cord at C. It will be seen that'when the engineer pulls the rope the trigger is pulled and the weight or spring released and the brake instantly closed. The slipping of the ring at F is of the utmost importance as all the brakes will be actedon whether the cars are drawn apart on an ascending grade or close together on a descending grade. At the top of the brake wheel is a clutch which when thrown up, the brake is opened or closed in the usualway.

I do not claim the use of springs or weights to operate the brakes of a car nor do I claim the use of a cord or its equivalent to act upon such springs or weights or directly upon the brakes neither do I claim the use of a cord for the purpose of transmitting signals from the rear of the train a to the engineer Without operating the brakes.
